msc meraviglia from New York 7 days

Planning to take MSC Crise Meraviglia in 1st of Nov from New York for 7 days with my family. I have done Royal caribbean earlier but MSC is 1st time for me and not very sure if 7 days worth entertainment and food options will there. We are vegetarian family, also how many heated pool MSC Cruise has as it's going to be cold in Nov when we start from New York
